-Trivial is not trivial.

1. A DC to AC cold cathode fluorescent lamp inverter circuit comprising:

a plurality of switches for selective coupling to a voltage line;

a transformer having a primary side and a secondary side, said primary side for selective coupling to said voltage line in an alternating fashion through said switches;

a feedback signal line receiving a feedback signal indicative of an electrical condition at a cold cathode fluorescent lamp load; and

a feedback control circuit coupled to said feedback signal line and said switches for adjusting the power delivered to said load only if said electrical condition is outside a predetermined range.
